Here are some possible questions that could be asked

Can you commit to discuss with the committee in a closed session the reasons for your recusal from the Russia investigation?

How many meetings did you have with the Russian ambassador or any other Russian officials in 2016? What were the topics discussed? And why did you fail to provide information about the meetings you had with Russian Ambassador Sergey Kislyak on your security clearance form?

What was your involvement in the decision to fire James Comey? Did you ask your deputy attorney general to write a memo recommending the firing of Comey? And if so, did he know it would become public?

Were you aware of Jared Kushner's contacts with Russian Ambassador Sergey Kislyak and were you aware of his interest in setting up a back channel during the transition? In general, do you think outreach to foreign governments should be coordinated with the outgoing administration during a transition?

Invoking executive privilege

There is a way that Sessions could skirt around having to directly answer these questions, however.

The White House on Monday suggested Sessions could invoke executive privilege during his testimony depending on "the scope of the questions."

Senate Majority Whip John Cornyn, an intelligence committee member, said senators were still deciding whether Sessions would be asked to testify in a classified briefing after the public hearing.
